United States Patent 3,208,782 WEATHERPROQF SLIDING WINDOWS LawrenceZeller, RR. 3, Harmon, Ontario, Canada Filed May 31, 1962, Ser. No.199,054 1 Claim. (Cl. 292-2515) The present invention relates to aholder and lock for sashless windows and it consists in thecombinations, constructions and arrangements of parts herein describedand claimed.

Generally the invention comprises novel devices for holding and lockingwindows of the sashless type where panels of plate glass are mounted toslide past each other in a frame and without a sash encasing the glasspanels themselves. The invention contemplates the use of an upper andone or more intermediate holding devices of novel structure whichutilize permanent magnets and lower locking and holding device likewiseusing a permanent magnet and having a novel locking structureincorporated therewith. The invention permits the secure holding ofhorizontally sliding panels in their closed position and also permitsthe secure locking of such windows when desired.

It is accordingly an object of the invention to provide a novel holdingdevice and lock for sashless windows.

Still another object of the invention is to provide a device of thecharacter set forth which is simple in construction, inexpensive tomanufacture and yet effective and etiicient in use.

Another object of the invention is to provide, in a device of thecharacter set forth, novel locking means forming a part of theinvention.

Still another object of the invention is to provide, in a device of thecharacter set forth, novel means for mounting the component partsthereof upon sashless windows.

Other and further objects of the invention will become apparent from areading of the following specification taken in conjunction with thedrawing, in which:

FIGURE 1 is a vertical sectional view of a pair of cooperating sashlesswindows illustrating the devices of ,the present invention mountedthereon,

FIGURE 2 is an enlarged vertical sectional view of a holding deviceforming a part of the present invention,

FIGURE 3 is an elevational view of a closure disc utilized in the deviceof FIGURE 2,

FIGURE 4 is an enlarged fragmentary vertical sectional view, partly inelevation, of a holding and locking device forming a part of theinvention,

FIGURE 5 is an elevational view of a closure disc utilized in the deviceillustrated in FIGURE 4,

FIGURE 6 is a fragmentary sectional view, partly in elevation, of thedevice illustrated in FIGURE 4 but taken at right angles thereto, and

FIGURE 7 is a sectional view taken substantially along line 7-7 ofFIGURE 6.

Referring more particularly to the drawing, there is shown therein apair of horizontally slidable sashless windows 10 and 11 and in thevertical cross sectional view shown in FIGURE 1, there is generallyindicated at 12, 13 and 14, respectively, an upper holder, anintermediate holder and a combined holder and lock.

Extending through a suitable opening in the window 11 is a cylindricalhousing 15 of stainless metal or suitable plastic material encasing apermanent magnet 16. The window 11 is countersunk, as indicated at 17,to accommodate an annular flange of the casing 15 and it will be seen byreference to FIGURE 2 that the outer face of the flange 18 and the outerface of the magnet 16 are flush with the adjacent face of the window 11.The casing 15 is held fixed in position by means of a collar 19 aflixedto the casing 15 by means of pins 20 or the like.

3,208,782 Patented Sept. 28, 1965 ice A steel disc 21 is mounted in acountersunk opening 22 in the inner face of the window 10 and iscentrally provided with an integrally formed stud 23 which extendsthrough an opening 24 in the window 10 and has threaded thereon at itsouter end a locking nut 25. It will be seen that the outer face of thedisc 21 lies flush with the inner face of the window 10.

The combined holder and lock 14 is illustrated in greater detail inFIGURES 4 to 7, inclusive, and consists of a cylindrical housing 26having centrally and longitudinally mounted therein a tubular member 27.The inner end of the housing 26 is provided with an annular flange 28suitably countersunk in the outer face of the window 11 and a permanentmagnet 29 of annular form surrounds the tubular member 27 and isencompassed by the easing 26.

A collar 30 secured by pins 31 or the like to the casing 26 acts torigidly hold the member 14 in position in the window 11 and it will beapparent that the outer faces of the flange 28 and magnet 29 lie flushwith the outer face of the window 11.

Countersunk in the window 10 is a disc 32 of steel or other magneticmaterial having a stud 33 extending through an opening 34 in the window10 and having threadably mounted thereon at the free end thereof alocking nut 35. A recess 36 extends centrally through the plate 32 andinto the stud 33.

Adjacent the inner end of the tube there is provided a pair of bayonetslots 37 and, inwardly of the slots 37 there is provided a pair ofdiametrically opposed inwardly directed arms 33.

A lock shaft 39 having an operating handle 40 at its outer end centrallyextends through the outer end of the casing 26 and through the tube 27and has fixed thereto at its inner end a collar 41 from which extends apair of diametrically opposed pins 42 each receivable in one of thebayonet slots 37. A compression spring 43 surrounds the shaft 39 andbears at one end against the arms 38 and at its other end against a pin44 affixed to and extending through the shaft 39 immediately inwardly ofthe outer end wall of the cylinder 26.

In operation, it will be apparent that when the windows 11 and 10 arebrought to closed position, the upper and intermediate holder members 12and 13 will register with their respective plates 21 and that themagnets 16 will coact with the plates 21 to hold the window in suchclosed position. This is also true, of course, with respect to the plate32 and magnet 29 in the combined locking and holding device 14. When,however, it is desired to lock the windows 10 and 11 in their closedposition, it is only necessary to grasp the handle 40 and move the shaft39 thereby until the free end thereof enters the recess 36 in the stud33, thereafter turning the handle 40 to move the pins 42 into lockingengagement in the bayonet slots 37. To unlock the windows 10 and 11, thepins 42 are disengaged from the bayonet slots 37 by twisting the shaftby means of the handle 40 in the reverse direction thus freeing the pinsfrom engagement with the circumferential extending portions of thebayonet slots to the longitudinally extending arms thereof thuspermitting the compression spring 43 to move the shaft 39 out ofengagement with the recess 36 and the stud 33.

It will be apparent that in the case of large windows one or moreintermediate holder members 13 may be employed whereas in a case ofextremely small windows, the intermediate holder members 13 may not benecessary.

While but one form of the invention has been shown and described herein,it will be readily apparent to those skilled in the art that many minormodifications may be made without departing from the spirit of theinvention or the scope of the appended claim.

What is claimed is:

A weatherproof holder for a pair of co-operating sliding sashlesswindows having opposed surfaces facing one another in closely overlyingrelation, and comprising; a cylindrical casing mountable in one sideWindow and of a length greater than the thickness of said window; oneclosed and one open end on said casing; an annular retaining flange ofgreater diameter than said casing extending outwardly therefrom in aplane substantially normal to the axis thereof around said open end forretaining said casing in position in said window with said flange flushwith an opposed surface thereof, said flange being of a thicknesssubstantially less than the thickness of said window; an annular collarmember slidably mountable around said casing for abutting against theother suurface of said window and retaining said casing in positiontherein; fastening means in said collar member for attachment thereof tosaid casing; a permanent magnet mounted in said casing; one end of saidmagnet exposed at said open end of said casing and lying in a commonplane with said annular flange and forming a flush surface therewith; acircular plate of permeable material of a diameter substantially equalto the diameter of said annular flange, mountable in the opposed surfaceof the other said window and of a thickness substantially less than thethickness thereof and having a contact face on one side thereof; athreaded stud of reduced diameter in relation to said plate extendingfrom the other side thereof and of a length greater than the thicknessof said window; threaded means for engaging the free end of said stud.
